Error:

- all:56 - Element does not exist and may not be modified


Resolution:

Typically this error can be returned when there is no matching identifier in the account to modify or list an item. Sometimes this could be caused if the identifiers (sku or guid for example) have leading zeroes and if they are exported and saved after that without formatting those values to text, the zeroes might be removed in Excel. An example could be if the GUID of an item in the account is 012345 and if a bulk relist file has been sumbitted with a GUID value of 12345, then the error would be returned because the value is different.
